vMOLD FASTENER.

Application filed August 19, 1926. `Serial No. 130,175.

' f vide a mold wall fastenerembodying wedge connected members which are constructively arranged so that one member may bead-,- justed laterally or vertically relative to the other member, thus permitting of a mold wall panel orthe like being adjusted and manipulated relative to adjoining mold walls or panels; -Thisis essential in order that mold walls may be assembled relative tonne another to form a mold cavity, particularly where the mold walls are at Yan angle relative to eachother. a

A further object of this invention is to provide interlocking ymembers or the adjoining edges of mold walls, said members permitting of one wall being easily land accurately seated on lthe other wall, and one of said interlocking members prevents the accumulation of water at said interlocking members to cause rust which might interfere with the joiningv ofthe mold walls. j

The above and other objects are attained by a simpleand durable lfastener that will be hereinafter specificallyl described and then claimed, and reference will now be had to the drawings, wherein Figure 1 is a front elevationof a mold wall fastener in accordance with this invention; n v.

Fig. 2 is a longitudinal sectional view of the same;

Fig. 3 is a detail sectional view of the linterlocking members of mold walls;

Fig. 4 is an edge view of one of the interlocking members;

Fig. 5 is a horizontal sectional view of mold walls connected in accordance withthis invention and arranged to provide a mold cavity, and

Fig. 6` is a front elevation of a Amold wall or panel equipped with fasteners in accordance with this invention; s l In vthe drawings, land 2 denote. adjoinj ing mold walls, panels or the like which have confronting edges beveled or cut on a bias,

as at 3..

Riveted, spot to thebeveled edge of a wall 1 is a strip welded or otherwise secured member 4 and likewise secured tothe wall 2, adjacent the beveled edge thereof, is a strip member 5. This member has a plurality of depressions or bosses 6 which are secured to the wall4 2 to maintain the strip member 5 in spaced relation to said wallso as to provide a drain space between the strip member 5 and the wall 2. That edge of the strip member 5 adjacent the edge of the'wall` 2' is flared outwardly or flanged, as at 7, lto cooperate with the wall 2 in forming a longitudinal pocket 8 to receive the edge of the strip 4, the strips 4 and 5 interlocking andcooperating inmaintaining the walls 1 and 2 inr a common plane so that said walls cannot become accidentally vdisplaced relative to each other, particularly by pressure exerted at the inner side ofeither-Wall. lhese interlocking strips are adapted toeX- tend throughout the length of any 'edges of a wall or panel, but according to Fig. 6. it

is Prfefabl terrevide a renew with two of the strip members 4 and two of the strip` members 5, the strip members 5 being arranged in opposed relation to the strip members 4 to facilitate assembling through the panels about the edges of the panel 9. Of

course, all of the edges of the panel 9 may be equipped with similar strips and adjoining panels with other strips, but when a mold wall is composed of many panels I find that the panels can be more rapidlyy and accurately assembledif equipped as shown in Fig. 6.

At suitable intervals along the edges kof the walls/ or panels are arranged fasteners comprisingy-Jopposed bracket members 10 and 11. Thev bracket member 10 may abut the edge of the strip member 4 and said bracket member has an., apertured lug 12 and slotted spaced apart arms 13. .The bracket member'll has an aperturedlug 14 and a single slotted arm 15 adapted to eX- tend between the arms 13 so that portions of the slots of said arms may aline and permit of a wedge or key 16 being driven in the slots of the arms 13 and 15 to draw the bracket members 10 and 11 towards each other. The wedge or key 16 may be in various formsso that it cannot become accidentally disengaged from the bracket arms and by driving the wedge into said arms the interlocking strip `members 4 and 5 will be drawn vtogether until the edges ot the walls 1 and 2.actually abut and form a 'good joint.

On the bracket arm l5 is an apertured lug 17 alining with the lug 14- andin said lugs is; a pin 1S having a tapered end l0 adapted to enter the aperturcd lug lf2. This pin is adapted to secure the bracket members .l0 and ll in opposed relation and assist in shifting the mold wall to establisb sncli bracket relation should one mold wall be. laterally displaced relative to the other. The tapered end 19 of tlie pin 18 assists in shitting the mold wall and its bracket relative to tbe pin carrying bracket.

To prevent the pin 1S from becoming accidentally displaced relative to tbe apertured litige 14 and 1T. said pin has n stop pin .20 between the lugs ll and fl?.

In using these fasteners 'for @recurring adjoining; welle or panels together it is pret` erable to arrange tbe same as eliown in Fig. 6 where two single arm brackets and two double arm brackets; are need on a single panel with the Sing-le arm bracketf-s opposite the double arm brackets.

ln Fig. 5 l show mold walls or panels assembled and articulated to l'orm a mold caritaY 2l adapted to receive plastic 1na'terlal l'or tbe formation ol a concrete wall or the like and it will be noted that the mold panels compoeing each inold wall are locked together so that the panels will provide smooth inner laces. lt is practically ixnpossible for one panel to become lateralhY displaced relative to adjoiningT panels `and it is by virtue et tlie panels that the panels can be quickly :resembled and just an readily die mbled so that the panels may be repeateoly need in tbc 'lorniation oil concrete structures.

Somewhat similar wall or panel 'fasteners are disclosed in my pending application 'tor mold 'torina liled Feb. 9, 19525,. Serial No. T,878 and allowed Feb. 28. 1926. This application may be ycons-idered a division et tbe sublect matter dieclosed in my former application.

`What I claim ie:-

l. The combination ol' meld walls` placed edge to edge. fastener brac-kette` adjacent tbe edges ot said mold walls, Slotted arme carried bj seid brackets, and a wedge extending through said slotted arme and adapted for drawing said brackets towards each other.

2. The combination called for in claim l, wheren tbe bracket arms are three in number with one olI` Said bracket arms extend# ing between tbe other two.

3. The combination called for in claim l, and a centering pin carried by one olf said brackets and adapted to enter tbe other bracket.
